从控制器Yii会话重定向后无法正常工作

Question

After save a model i want to store a model auto increment id in a session variable and redirect to a view page. When i want to echo that session variable in view page it is not working.

Note: I don't use user login/logout system.

In config.php

'session' => array(
        'autoStart'=>true,
        'timeout'=>1200,
    ),

In Controller File

if ($model->save()) {
    Yii::app()->session['orderId']=$model->id;
    $this->redirect(array('view', 'id' => $model->id));
}

In the controller where i use redirect() if i use render() then it's work. After redirect it's not working.

In View File

echo Yii::app()->session['orderId'];

Please Help Me :(

Answer 1

You can store session data with

if ($model->save()) {
Yii::app()->user->setState('orderId', $model->id);
}

Get it with

echo Yii::app()->user->getState('orderId');

Answer 2

Try this ,

in your controller

if ($model->save()) {
    Yii::app()->user->setState("orderId",$model->id);
     $this->redirect(array('view', 'id' => $model->id));

}

//get session variable

Yii::app()->user->getState("orderId");

尝试在重定向之前添加“返回”：

return $this->redirect(array('view', 'id' => $model->id);
